I was in that same boat with my micro models. It got to where I felt like I had to add X, but to add X properly it felt like I also needed to handle Y, and so on and so on. So I get the struggle! I can have a problem of not knowing when and how to set the level of abstraction and not let the perfect be the enemy of the good. I have so many scrap projects that stall out because of this. And proletariat science unfortunately has to deal with the fact that we have other jobs that take away our time.

I will give it another look now that I understand what you were doing with the 1000 prices and that you did disaggregate. It isn’t bad code, it just isn’t my first language!

Don’t know when I will get back, but I hope do it soon as I genuinely love this sort of stuff!
